Slave Trade Compromise
In order to please the large and the small states, the Connecticut Compromise was created. Congress became a bicameral legislature, consisting of the Senate and the House of Representatives. The Senate gave each state two votes, and the House of Representatives gave states votes based on their populations.
Large states believed that in order to have fair representation in Congress, states should be given votes based on their population size; small states get fewer votes and large states get more votes.

The Trade Compromise "solved" the issue surrounding slave trade in the United States. States in the North wanted Congress to have the power to regulate commerce, but states in the South feared this power because they though Congress would end slave trade. They reached a compromise that stated that slave trade could not be ended until 1808, but imported slaves could not be taxed.
The 3/5ths Compromise determined the number of representatives each state was given in the House of Representatives. The southern states wanted slaves to count towards their population so they could have more representatives, but northern states did not because this would mean that the southern states would have more representation. They reached a compromise that stated that 3/5ths of slaves would count towards each state's population.
One of the weaknesses of the Articles of Confederation was the lack of a chief executive of the United States. Once it was settled that there would be a president, the election process had to be created. The Electoral College Compromise was created; it stated that the president would be elected through representatives in Congress.
